At the scene of a crime, you find three patterns of blood spots. You measure the following lengths and widths for each spot:
1. Spot A pattern: Length = 4.0 mm, Width = 4.0 mm
2. Spot B pattern: Length = 3.0 mm, Width = 1.5 mm
3. Spot C pattern: Length = 5.0 mm, Width = 1.0 mm
Angle of Impact = ArcSin (width/length)
Use the formula given above to determine the angle of impact for each of these three bloodstain patterns. Which dropped from a point directly overhead? Which impacted at the sharpest angle? As a blood spatter analyst, how would you interpret and use this information? Explain.

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.
